To the end therefore of providing a siniple last structure and one capable oi eco` noinical production with n maximum rigid ity and strength. l-have devised iny present i vention. in it l use novel form of link or hinge connection for the fore and heel which has heen shown to he highly and practical for the purposes inefiicient tended.

The construction and operation of will he more fully sct forth in the speciication that follows and as illustrative of i'ny invention, i have shovvn in the drawings, several embodiments ot my device which have heen found well adapted to practical use. f

Throughout speciiication and drawings, like reference nmnirals are employed to indicato corresponding parts. and in these dra .'in f Figure l. is a central longitudinal section through a last in accorda-nce with my invention and indicating in dotted lines a partial showing ot' the hccl section position when the last is collapsed, lack of space.

Fig. 4 is a transverse section on the line 4 4: of Fig. l looking in the direction of the arrows. Fig. 5 is a. partial section of a inodilied embodiment in which l use a locking latch to hold the last sections in expanded position. Fig. (S a partial section of another modiiication.

un "l El ot' intersection ond at they bottom f The fore *gli* nas a. face tl and olined tace at a. point with the npner e-:lge of of the heel part and tli-.1u er included between the respekt; intersection of the faces o and the aces (i and 7 define a substantially l-shaped space which permits the faces l and 7 to contact Wncn the face 5 rides up along the face G, as partially shown in dotted lines Fig. The face 7 is therefore a stop :tace to limit the upward movement of the heel part. i The heel part has a bore it near its bottoni starting from the 'facel and running nach as far as the jock hole l0 and thc i'ore part has somewhat sectorshaped recess extending from its rear tace The hinge or link connection which 'permits the heel n moved relatiife to the fore port s r the bore of the heel part and @voted recess of the fore part so an up and clown play therein, This connection is torined as linlr. having a cylindrical. body portion S pinned in the heel part just forward of tl e jack hole 1U by a ti 1l. Near the curved -t'ace 5 the heel part the body portion S has a iin iiecting therefrom to prevent its turning laterally and said cody portion is also shouldered at l2 to provide a narrow shank 13? preierably rectangulaiin cross section as shown. This shank near its forward end is pivoted in the fore part by a transverse pin L1 and lits and is guided in a channelejt guide nieinicer seated in and suostanti l conforming. to the sector shaped recess of the fore port. Said guide member com rises a. bottom strip tapped through linsverse pin i 15 and integral side walls 16 which define a substantially U-shaped recess 17. The guide member is pinned within the fore part at its forward end by the pin 14 of the shank which passes transversely through the side walls 1G.' Aldjacent to the pin 1l the walls 1H are extended upu'ardlyfin the form of substantially sector shaped wing pieces 18. The rear faces of these wings are curved to conform te the curvature oi' the rear face G of the fore part and have as their approximate center the pin 1J: which pin also represents the approximate center for the curve on which theface 6 is sawed. These curved faces of the wings project slightly beyond the face 6 as tongues 19 and are adapted to t within registering grooves 20 in the curved face 5 of the heel part. These grooves 2O extend from end to end of the face 5 and therefore provide a double tongue and groove connection for `the heel and fore parts. The narrow forwardly projecting tongue of wood 21 left between these grooves enters within the channel 17 formed by the bottom strip 15 and sidel walls 16 of the guide member to frictionally engage the inner faces of the tongues 19 of the' Wing pieces. The shoulders 12 of the shank limit the downward movement of the heel part by striking against the wood of the heel part left when the boi'e is tapped therethrough.

The operation of this type of last is substantially as follows: The last is normally in the position shown in Fig. 1 in which position the bearing faces ,5 and 6 lie in contact with each other after the manner of a knuckle andsocket joint. When it is desired to collapse the last the heel part is thrust upwardly causing the face 5 to ride up along the face 6 in an arcual path. In this movement the heel part is guided along the fore part by the tongue and groove connections 19 and 20 and 17 and 21 until the forwardly inclined face 4 of the heell part abuts against the rearwardly inclined stop` face 7 of the fore part. While the heel part is describing this movement relative to the fore part the shank 13 is being swung upwardly on its pivot in the fore part and Works in the space 17 between the lateral wings 18 reaching the limit of its movement when the faces l and 7 of the last parts contact.

The frictional engagement of the tongue and groove connections hereinbefore described is sufficient under ordinary conditions of use to hold the last parts in lasting position, but under certain conditions it -is expose one end of a pivot pin `23 and provide working space for a late-hingy device. This latch is yin the form of a link 24 Whichi'is pivotally mounted on the pin 23 and is provided near its upper end with a locking notch 25 adapted for engagement over a secf' Y 'ond pin 26 fastened in the wood of the fore part. The free end of this latch projects up into the V-shaped space between the faces` operative. e 'ln Figs. 6 and T I have illustrated as anand '7 so as to be easily accessible to they other embodiment a form of conn'ection espe- 1 cially designed to give an increased bearin to the shank to successfully resist the breaking down strain of the sole leveler. The nose 27 of the shank is in this embodiment slightly tipped up in the manner of a hook to engage over a transverse pin 28 in the" wood of the fore part. This engagement not manner of securing the guide member in the fore part by a second pin 29 which is inde-` pendent of the shank '13.

These and various other modifications` coming within the spirit of my invention may obviously be resorted to within the limits of the appended claims.v

What I therefore claim and desire to se` eure by Letters Patent is:

1. A last of the class described comprising a fore part and a heel part having suitable bearing therebetween, a guiding member in,

one of said parts having a slot vertically disposed therein. and a link pivoted at one end in said partand located within the slot of said guide and having its other end fixed in said other part, the edges of said ide extending beyond the bearing surface o said first named part, the bearing surface of saidr second named part being grooved to receive j said projecting edges to guide the same: Y

2. A last of the class described comprising a fore part .and a heel part havingvcoperatino` bearin faces one of said arts havin a gi'ooved face, a channeled guiding member in the other part having its edges exposed to engage said grooves, and a connection iv-` oted at one eid in said part andlguided with-k in the channel of said guide and having its 1 other end fixed in said other part.

3. A last of the class described comprising a fore part and a heel part having/suitable bearing surfaces therebetween, the bearing surface of one of said parts being grooved,'a. ,A guide member located inthe other of said parts andhaving its edges exposed to have throughout the movement of the parts, a link pivoted in sai guide at one end and fixed in the co"perating last part at its other end, and shoul ers on said link engaging the exposed edges of the guide member.

4. A last ofthe class described comprising continuous engagement in said grooves ist lessees l fa oi'e partfmid a heel peri: having suitable Vbearing sureees therebetween, a guiding f member iugoiie f Vsaid parts and having a slot vertieeliy Yiispesed therein, and a link 5 pivoted in @id guiding member and fitting Withinitdhe Biot thereof, said guiding member having its edges exposed an curved concen- .V trie-with Ithe pivot of said link, said link having shoulders slidabiy engaging the exposed edges of said giiiding member and arl GEGRGE EDWARD BELCHEE.
